Yes, I was first put on letrozole And had terrible joint and muscle aches and just did not feel good this was after one month , Took a two month break and then was put on exemestane , Felt even worse after a month Also, I started feeling terrible and it just Got worse, have terrible, terrible carpal tunnel and neuropathy in my hands because of these pills, Since getting off of the pills which both pills I was only on each one, a total of three months each, I am going off all of them for a While, I met a girl a couple girls actually that take these pills every other day or three times a week and feel much better, they can tolerate them much better. I may consider just trying that, my oncologist radiologist said very few people can take these pills without bad side effects. I did not have bad breast cancer( I guess I can put it that way.) It was a stage one. I may just take my chances I keep my fingers crossed, since I’ve been off the pill now it’s been about 2 1/2 weeks. My hands have improved greatly, all body aches and pains are gone, so I know it’s these pills at the end of the day. I do not want to feel as bad and achy as I was…I’m going to think about it and possibly do one pill three times a week. These girls said their doctor said something was better than nothing. My doctor did Not Agree .. but have not really cared for my doctor from the beginning, his mindframe is his way or no way.. does not really work with you well which is not fair you have to become your own advocate I guess and do what’s best for you, I’m sure there are a lot of girls that can take these pills perfectly fine. I unfortunately am not one of them.
